Q: certificate error navigation blocked IE9 can't continue

When I get the certicate error and then select to continue on to site I don't get any response.  In previous versions of IE I could at least continue on to the site but now I am unable to do so.  Have not found any thing in forums that gives a solution.  Tried to download and re-install IE9 but got error that I have a newer version already installed.



try folowing

1) run cmd as administrator

2) execute string:

certutil -setreg chain\EnableWeakSignatureFlags 8

3) restart computer

4) after doing so you will be able to continue working with your site inspite of certificate problem

Did this solve your problem?

Sorry this didn't help.

Hi NavyIT,


1) Have you made any changes to your computer recently?
2) Which is the antivirus software that is installed on your computer?

This issue can occur, if-

a) A certificate is blocking you from visiting the particular website.
b) The antivirus is blocking you from visiting the website.
c) There are viruses on your computer.

Method 1 –

You need to disable the antivirus and the Windows Firewall.
To disable the Windows Firewall, you may follow the steps from the article mentioned below –

Note: Make sure you Turn On the Windows Firewall after following all the steps.

Method 2-

You need to Run an Online Virus Scan to check for viruses.
To do so, you need to download the antivirus from the link mentioned below –

Note: The antivirus might find bad sectors on the hard drive while scanning and will try to repair these sectors. Any data on these sectors might be lost.

Method 3 –

You can try removing the certificates from the Internet Explorer manually.

To do so, you need to follow the steps mentioned below –

a) Open Internet Explorer.
b) Click on “Tools” and then “Internet Options”.
c) Select the “Content” tab and select “Certificates”.
d) Delete the Certificates that are causing the issue.
e) Restart Internet Explorer and try again.
f) If the issue still persists then go back delete the other Certificates present since there might be other Certificates in the hierarchy that need to be deleted first.
g) Restart Internet Explorer once again.
